Right atrial and ventricular clot as a cause of peri-arrest during caesarean birth requiring immediate thrombectomy.

Venous thromboembolic disease remains a leading cause of maternal morbidity and mortality. We report a case of a 30-year-old woman at 37 gestation with a history of thalassaemia intermedia and splenectomy. During pregnancy, she had been managed with frequent blood transfusions and enoxaparin.

An Information-Theoretic Method for Identifying Effective Treatments and Policies at the Beginning of a Pandemic.

Identifying effective treatments and policies early in a pandemic is challenging because only limited and noisy data are available and biological processes are unknown or uncertain. Consequently, classical statistical procedures may not work or require strong structural assumptions. We present an information-theoretic approach that can overcome these problems and identify effective treatments and policies.

What is the Role of Spatial Attention in Statistical Learning During Visual Search?

Our ability to learn the regularities embedded in our environment is a fundamental aspect of our cognitive system. Does such statistical learning depend on attention? Research on this topic is scarce and has yielded mixed findings. In this preregistered study, we examined the role of spatial attention in statistical learning, and specifically in learned distractor-location suppression.

Peripartum dissociation, sense of control, postpartum posttraumatic stress disorder and emotional adjustment to motherhood in adult survivors of childhood maltreatment.

Survivors of childhood maltreatment (CM) may experience difficulties in the peripartum period and in adjustment to motherhood. In this study we examined a model wherein CM is associated with maternal self-efficacy and maternal bonding three months postpartum, through mediation of peripartum dissociation and reduced sense of control during childbirth and postpartum-posttraumatic-stress disorder (P-PTSD). Women were recruited in a maternity ward within 48 h of childbirth (T1, N = 440), and contacted three-months postpartum (T2, N = 295).

High inter-rater reliability between physicians and nurses utilising modified Downes' scores in preterm respiratory distress.

Aim: To assess the inter-rater reliability of modified Downes' scores assigned by physicians and nurses in the Ethiopian Neonatal Network and to calculate the concordance of score-based treatment for preterm infants with respiratory distress.

Methods: We included preterm infants admitted from June 2020 to July 2021 to four tertiary neonatal intensive care units (NICUs) of the Ethiopian Neonatal Network that presented with respiratory distress. We calculated the kappa statistic to determine the nurse and physician correlation for each component of the modified Downes' score and total score on admission and evaluated the concordance of scores above and below the treatment threshold of 4.

The impact of the early onset neonatal sepsis calculator on antibiotic initiation: a single center study in Israel.

To evaluate the effect of implementation of the Kaiser Permanente (KP) early onset sepsis (EOS) calculator in infants born at 34 week's gestation or more on antibiotic utilization and length of hospitalization. A single center, retrospective cohort study included all neonates born in Soroka Medical Center at 34 weeks gestation or more between January 1, 2015, and January 1, 2019, with a predefined maternal risk factor for EOS. Two cohorts of neonates were compared during two time periods, before and after the implementation of the KP calculator.

Impact of an Online Program of Bubble Continuous Positive Airway Pressure Education in a Resource-Constrained Setting.

Background: Respiratory distress is a leading cause of preterm infant mortality in sub-Saharan Africa. Bubble continuous positive airway pressure (CPAP) is emerging as a potentially safe, cost-effective way of delivering noninvasive respiratory support in low-income and middle-income countries. However, without healthcare providers who are knowledgeable and skilled in the use of this technology, suboptimal neonatal care and related health disparities are likely to persist.

Attentional guidance by target-location probability cueing is largely inflexible, long-lasting, and distinct from inter-trial priming.

There is growing consensus that selection history strongly guides spatial attention and is distinct from current goals and physical salience. Here, we focused on target-location probability cueing: when the target is more likely to appear in one region, search performance gradually improves for targets appearing in that region. Probability cueing is thought to reflect a long-lasting, inflexible and implicit attentional bias.

Is Statistical Learning of a Salient Distractor's Color Implicit, Inflexible and Distinct From Inter-Trial Priming?

Being able to overcome distraction by salient distractors is critical in order to allocate our attention efficiently. Previous research showed that observers can learn to ignore salient distractors endowed with some regularity, such as a high-probability location or feature - a phenomenon known as distractor statistical learning. Unlike goal-directed attentional guidance, the bias induced by statistical learning is thought to be implicit, long-lasting and inflexible.

Information theory: A foundation for complexity science.

Modeling and inference are central to most areas of science and especially to evolving and complex systems. Critically, the information we have is often uncertain and insufficient, resulting in an underdetermined inference problem; multiple inferences, models, and theories are consistent with available information. Information theory (in particular, the maximum information entropy formalism) provides a way to deal with such complexity.

Understanding the Constraints in Maximum Entropy Methods for Modeling and Inference.

The principle of maximum entropy, developed more than six decades ago, provides a systematic approach to modeling inference, and data analysis grounded in the principles of information theory, Bayesian probability and constrained optimization. Since its formulation, criticisms about the consistency of that method and the role of constraints have been raised. Among these, the chief criticism is that maximum entropy does not satisfy the principle of causation, or similarly, that maximum entropy updating is inconsistent due to an inadequate representation of causal information.

Early versus late-onset necrotizing enterocolitis in very low birth infants in the neonatal intensive care unit.

Background: Necrotizing enterocolitis (NEC), one of the most severe emergencies in neonates, is a multifactorial disease with diverse risk factors.

Objectives: To compare between the clinical and laboratory characteristics of premature infants diagnosed with early-onset NEC (EO-NEC) and those with late-onset NEC (LO-NEC).

Patients And Methods: Enrolled infants were identified from prospective local data collected for the Israel National very low birth weight (VLBW, < 1500 g) infant database and from the local electronic patient files data base for the period 1996-2017.

Does the U.S. Navy's reliance on objective standards prevent discrimination in promotions and retentions?

To prevent discrimination, the U.S. Navy enlisted-personnel promotion process relies primarily on objective measures.

The Added Value of SOX10 Immunohistochemistry to Other Breast Markers in Identifying Cytokeratin 5-Positive Triple Negative Breast Cancers as of Mammary Origin.

Aims: Triple-negative breast cancer (TNBC) represents a specific group that lacks the expression of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor-2 and might also lack the expression other breast markers like GATA3, mammaglobin (MG), GCDFP15 (growth cystic disease fluid protein 15), and NYBR1; when this occurs, proving the breast origin of a metastasis is a challenging task. In the present study, we assessed the added value of SOX10 immunohistochemistry to known GATA3, MG, GCDFP15, and NY-BR-1 statuses in a series of CK5-positive primary TNBCs.

Methods: Tissue microarrays were made from the formalin-fixed and paraffin-embedded blocks of 120 TNBCs, and 3-4-mm-thick sections were immunostained for SOX10.

Clinical Application of Postmortem Magnetic Resonance Imaging in Neonates.

Background: Recent reports advocate the use of MRI either as a substitute for postmortem examinations or for a more targeted autopsy.

Methods: A full-body postmortem MRI (pMRI) of infants was performed as early as possible after death, and findings were compared to clinical premortem diagnoses.

Results: Thirty-one infants were scanned during the study period.

Interpreting Social Accounting Matrix (SAM) as an Information Channel.

Information theory, and the concept of information channel, allows us to calculate the mutual information between the source (input) and the receiver (output), both represented by probability distributions over their possible states. In this paper, we use the theory behind the information channel to provide an enhanced interpretation to a Social Accounting Matrix (SAM), a square matrix whose columns and rows present the expenditure and receipt accounts of economic actors. Under our interpretation, the SAM's coefficients, which, conceptually, can be viewed as a Markov chain, can be interpreted as an information channel, allowing us to optimize the desired level of aggregation within the SAM.

Implementing a Practical Global Health Curriculum: The Benefits and Challenges of Patient-Based Learning in the Community.

A growing number of medical schools across the world have incorporated global health (GH) into their curricula. While several schools focus GH education on lecture-based courses, our premise is that global health education should embody a holistic approach to patient care and medical education in local communities. Medical students may learn global health by focusing on real patients, their families and communities as part of a practical curriculum.
